Other comments: Bwanabwana or Tubetube has a quinary counting system. 20 was expressed by the phrase 'tau kaigeda simate', 'mate' is a shortened form of koyamate or unuyamate 'to kill', so twenty may mean 'they (prefix si-) killed one male/man'. However, the new generation are quickly losing the numerals of six and above (with the possible exception of sanaulu 'ten'), and tend to transliterate the English words.    

Bwanabwana is spoken by about 2,400 speakers in southeast Basilaki island, Engineer islands and nearby islands, in Bwanabwana district, Milne Bay province, Papua New Guinea.
